Be it known that L'FRANK L. HARMON, re

siding atBeverly,tin the county of Essex and Commonwealth of Massachusetts, have in vented a new and useful Machine for Skiving and Folding Leather, of whichthe following is a specification, reference being bad to the accompanying drawings.

v The object of this inventionis to produce a foldededge of apiece" of leather which is of about the same thickness as the piece of leather before itis folded; but the nature of this invention, exclusive of function which is 125 I feeding device may beactuated; a slitting denot a part of said nature,cannot be briefly and comprehensively disclosed without conveying ideas as follows in language substantially as follows: a skiving-knife adapted to skiveor bevel a piece of leather near-the edge of said leather; means whereupon said skiving-knif'e may be actuated; a feeding device adapted-to, move said leather a distance of about one-3 eighth of an inch toward said skiving k'nife in order that said leather may be skived or bev-; eled as far as said feeding device is adapted? to move saidleather; means whereupon said Vice adapted to cut a slit about one-eightliof an inchlong in the skived or beveled part,pro-

vided it be formed at aboutright angles to the skived or beveled part and in such a place that a part of the skived or beveled part near the thinnest edge of saidskived or beveled part may be adapted to be bent downward without bending any other part of the leather downward; means whereupon said slittingdevice' may be actuated; a beveled and recessed de-. "vice adapted to fold the part of said skivedpart adapted to be bent downward, provided it be formed and bent downward, and adaptedto rub the skived andbent part from the folded edge inward, provided said part be formed, 1 bent, and folded; means whereupon said folding and rubbing device may be moved in such a direction as to fold the part of said skived part adapted to beben't downward,ifsaid part be formed and bent downward, in a direction from the skived edge in ward and rub said part of the skived part adapted to be bent down- :ward in .adirection from the folded edge inward, if said part be formed, bent, and folded; a receptacle adapted to hold cement; means whereupon a proper amount of cement may said recessed ed to bebent downward and press it down upon a recessed part of said device adapted to fold and rub in order that cement upon part may be rubbed upon said skived part by said device adapted to fold and rub and also adapted to bend said part of said skived part adapted to be bent downward into a recessed part of said device adapted to fold and rub in order that said part of said skived part adapted to be bent downward may be folded by said device adapted to fold and rub and that the opposite side of said part of said skived part adapted to be bentdownward from the side on which cement is deposited, provided said skived part be bent and folded, may be rubbed by said device adapted to fold and rub; means adapted'to heat said device adapted to fold and rub to facilitate the folding of said. part of said skived part adapted to be bent downcement applied to said skived part; in combination with a grinding device adapted to grind said skiving knife whereupon said leather may be skived or beveled, and means whereupon said grinding device may be forced to grind said skiving-knife.

A machine in which this invention is embodied iscomprehensively shown in the accompanying drawings, and the especial features and novel mechanical combinations of parts shown therein will be hereinafter fully described and set forth, and claimed in the claims appended hereto.

In the accompanying drawings, Figure l istop plan view of the machine embodying thisinvention.

Fig. 2 shows a cross-sectional elevation on line a; as, indicated by an arrow at the left-hand corner of Fig. 1. Fig. 3 shows a longitudinal sectional elevation on line y y,

indicated also by an arrowat the left-hand corner ofFig. 1. Fig. 4 is a perspective detail view of a feeding device; and Figs. 5, 6, 7, and 8 show perspective detail views of devices whereupon thefeeding device is yieldingly supported and whereupon the feeding device may be manually adjusted or moved and secured at any necessary angle to the cutting edge of a rotatory disk skiving-knife, leaving the feeding device operative, thereby operatively holding the part of the feeding device which moves the leather at any necessary angle to the rotatory disk skivingknife, so that the piece of leather may be skived at the edge of said leather at any necessary angle. Fig. 9 shows a vertical section of a device by which a piece of leather is folded, so as to form a folded edge, and is rubbed in a direction inward from said folded edge in operative connection with a part of a cement-receptacle and devices connected therewith, whereupon a proper amount of coment is in practice taken out of said cementreceptacle. Fig. 10 shows the construction of a rod and a sleeve thereon whereupon the feeding device is moved in practice. Fig. 11 shows a vertical section of a wheel whereupon a grinding device is rotated V in practice for grinding a rotatory disk skiving-knife. Fig. 12 is a perspective view of a gas-burner for heating the device for rubbing the folded part of a piece of leather in a direction inward from the folded edge. Fig. 13 shows a perspective view of a cement-receptacle and devices connected therewith,whereupon a specific or proper amount of cement is in practice automatically taken out of said cement-receptacle. Ascertainpartsbywhichcementisautomatically deposited upon a device for rubbing the cement upon the skived part of theleather after the cement is automatically taken out of said cement-receptacle are obscured by many lines in Fig. 1, a detail plan of said partsis shown in Fig. 14, free from obscuring lines, in order that a comprehensive idea may be conveyed as to their construction and operation. Fig. 15 is a sectional detail in side elevation,free from obscuring lines, to more fully illustrate the parts shown in Figs. 3, l, and 14. Fig. 16 shows an end elevation of some of the parts shown in detail in Figs. 14 and 15 and also illustrates more fully than other views how that acover for covering the device for rubbing the cement upon the leather is secured to the frame of the machine. Fig. 17 is a sectional detail view in elevation to illustrate the construction of a brush or device for depositing the cement upon the device for rubbing it upon the skived part of the leather.

In the journal-bearings of the knife-shaft supportA, (shown in Figs. 1, 2,and 3,) rigidly but adjustably secured to the frame A as and for the'purpose hereinafter described, the

rotatory disk skiving-knife shaft A (shown in Figs. 3 and 2) i'sjournaled. The horizontal grooved wheel A (shown in Figs. 3 and 2) is secured upon said rotatory disk skivingknife shaft A. A round belt (not shown) operating in practice in the groove of the wheel A rotates said wheel A the rotatory disk skiving-knife shaft A secured thereto, and the rotatory disk skiving-knife A", secured to said shaft, with great rapidity. Attention is called to the fact that the power conveyed by this belt is exclusively applied to said wheelknife-shaft and knife, or, in other words, the knife-shaft is thereby operated independent of the means for conveying power to other parts of the machine. Said Wheel knife-shaft and knife are rotated independent of the power conveyed to the other parts of the machine, which comprise devices whereupon feeding, cementing, slitting, folding, heating, and rubbing are accomplished in order that it may be possible to raise the speed of the wheel A knife-shaft A and knife A to any desired speed from its normal speed to facilitate the skiving of some kinds of leather properly without affecting the speed of the rest of the operative devices of the machine, and a construction whereupon this could be accomplished not having been heretofore made the combination of means for rotating the knife-shaft and skiving-knife independent of the power conveyed to other operative parts of a skiving-machine in combination with the other operative parts of a skiving-machine in order that the speed of the knife may be raised without affecting the speed of the other operative parts of the machine is of my invention.

On the left-hand side of the frame or box A (shown in section in Fig. 3,) which box incloses the greater part of the operative mechanism of the machine, is the bracket A, secured to the frame or box A on the outside of the frame or box by two screws, one above the other, and said bracket extends toward the left at right angles to the frame or box A outside of the frame. This bracket is peculiar in shape, the lower end thereof being thejournal-bearing shown inside of the frame or box A near the left-hand lower corner of Fig. 3, in which journal-bearing the shaft A is journaled, and the upper end of said bracket being the journal-bearing directly above the first-named journal-bearing, also inside of the frame or box A in which lastnamed journal-bearing the shaft A is also journaled. Upon the 7 top of the shaft A, above the last-named journal-bearing, the device A for folding and rubbing the skived part of the leather is rigidly'securcd and is rotated in practice with said shaft. This device A is shaped like a disk and is beveled, as is shown in Fig. 9, in which figure the device A is shown in vertical section. Attention is called to the left-hand side of Fig. 1,

.to the outer circular line which describes the circumference of said device A,in order thata comprehensive idea of the size of this device maybe conveyed. Attention is also called to the left-hand upper corner of Fig. 2, at which place in said figure the device A, shown in elevation, is not obscured by lines, and attention is also called to the right-hand lower corner of Fig. 14:, where the device A is shown in plan, free from obscuring lines, and attention is also called to the right-hand upper cornerof Fig. 15, in which figure the device A is shown in section and is also shown securedto apart of the shaft A. Attention is 1 where the horizontal again called to the left-hand side of Fig. 3, grooved wheel A is shown secured to the shaft A. A round belt (not shown) operating in practice in the groove of said wheel A rotates said wheel A the shaft A, shown secured thereto, and the device A shown. for folding and rubbing the skived part of a piece of leather, and to which device attention has been called in the several views.

. Upon the shaft A, inside of the frame or box A at the left-hand lower corner of said frame, the eccentric or cam A is shown rigidly secured to the shaft A, which eccentric or cam is' rotated by the shaft A when the shaft A is rotated. Immediately above said eccentric or cam A A, one end of which is secured to a screw shown fast in the bracket A and the other end of which is secured to a screw shown fast inthe sleeveA which sleeve is shown fast to the rod A, which sleeve and rodare shown in detail in Fig. 10 shown belowFig. 3, and as said rod A is movably supported in the slideways A and A fast to the lower part of the frame A the coil-spring A moves said rod in practice and forces the left-hand end of said rod. (shown also in Fig. 10) cam or eccentric A that the rod A is moved in practice toward theright in the slideways A and A against the stress of the spring A by the eccentric or cam A when the eccentric A the upright shaft A and is moved in practice toward the left by the force of the spring A, which spring A movessaid rod A, and there- Therefore it is plain by forces the left-hand end of said rod to foltion to said rod and the sleeve A secured brated may be governed ing the check-nuts A A3, or,in other Words,

The construction lowthe face of theeccentric cream A, the cam and spring imparting a vibratory mothereto. The distance that the rod A is viby manually adjustand A on the righthandend of said rod and outside of the frame securing them in a position nearer the frame or box A shown in section near to said checknuts, thereby preventing said coil-spring A from moving the rod A any farther than the distance between the frame and said checknuts, thereby preventing the left-hand end of said rod from following the face of said cam throughout the movement of said cam, and thereby not allowing the cam A to move said rodA the full extent of the throw of the cam. The material or leather is moved in practice intermittently or step by step tothe skiving-knife and the folding and rubbing device, as and on account of devices hereinafter described, operated by power conveyed through said rod A. Therefore it is plain that said material or leather to be skived may be caused to be moved intermittently a greater or less distance by adjusting said check-nuts upon said rod A, as hereinabove described. and assembling of all of the secured to said shaft and is shown the coil-springagainst the" is rotated by manuallymoving and devices whereupon the feeding is accomplished except said rod A and said means whereupon said rod is moved in practice, as aforesaid, are described as follows: The feeding device A (shown in Fig. 4, whichfigure is shown below Fig. 1) is movably supported in practice between the prongs of the device A (shown in Fig. 5, which figure is shown at the right of Fig. 4,) the pin A (shown in the right-hand upper corner of Fig. 3) being inserted in the holes shown in the prongs of the device A and extending through the hole in the center of the feeding device A said pin fitting loosely in the hole in said feeding device A in the manner shown in Fig. 3. The

right-hand round part of the device A is inserted in the hole in the sleeve A ,as shown in Figs. 1 and 3, said round partfitting loosely in said hole, which sleeve A is shownnear to the end of the device A and thedevice A (shown in Fig. 7 at the right of the device A is secured upon the round part of the device A by the screw A (shown in the device A as shown in Figs. 1 and 3, said device A having the function of a collar and having a handle thereon, and the trunnions A and A of the sleeve A are placed in the round holes shown in the bracket A, which bracket is made fast to the frame A on the outside of the frame, the part A (shown in Fig. 5 below Fig. 1) and the feeding device A, movably secured to said part, extending through the frame A on the inside of the frame A as shown in the righthand upper corner of Fig. 3.

It will be observed by the description of the assembling of the parts whereupon the feeding is accomplished that the trunnions A and A of the sleeve A movably supported in the round holes shown in the bracket A (shown in Fig. 8,) form a construction whereupon the feeding device A (shown in Figs. 3 and 1) may be moved up and down. In order to prevent this feeding device A (shown in the right-hand upper corner of Fig. 3) from falling and turning the trunnions .A and A (shown in Fig. 6 under Fig. 1) in the round holes in the bracket A (shownin Fig. 8,) in which they are pivoted, as shown in IIO Fig. 3, and that the feeding device A may be yieldingly supported, vised. .The spring the spring A isde- A is secured to the part A, which part A is pivoted by the screw A to the bracket A, which screw A fits loosely in a hole in said part A andis firmly secured into the bracket A which bracket is fastened to the outside of the frame A by the screw A said bracket extending through the frame A and said spring A bears against the device A in which the feeding device A is movably secured, and thescrew A is threaded in the frameA and forced against the part A exerting force upon. the spring A, thereby causing said spring to hold the feeding device A in the position in which it is shown, and the screw A is secured in position by the check-nut thereon. The spring the A is prevented from forcing the feeding device A too high by the screw A threaded upward, the feeding device A is yieldingly supported, or, in other words, it may be pushed downward, causing the spring A to yield, which spring exerts force, whereupon feeding device A is normally held in its proper elevation, or in the elevation in which it is shown. It is also plain that the device A maybe manually turned or adjusted in the hole in the sleeve A by the handle of the device A (shown in Figs. 7, 3, and 1) and secured by the screw A in the sleeve A (shown in Figs. 6, 3, 2, and. 1,) thereby adjusting the feeding device A, movably sup ported in the device A, as hereinabove. described and as shown in Figs. 5, 3, andl, out of a vertical position and at any necessary angle to the cutting edge of the rotatory disk skiving-knife A", as shown in Figs. 2, 3, and 1.

Attention is called to the flange upon the feeding device A (shown in detail in Fig. 4 under Fig. 1,)

which flange extends out from the nearest side of said feeding device. At-

tention is also called to this flange in Fig. 2

on the left-hand side of said feeding device. Attention is again called to this flange in Fig. 3. The upper end of the lever A is grooved and fits upon the flange of the feeding device A but may be moved or slipped upon said flange. Fast to the upper end of the lever A is a hook, to which one end of thecoilspring A is shown secured, the other end of the coil-spring A being shown secured to a screw shown in the support A shown secured to the bracket A, which spring is shown expanded or stretched beyond its normal length, exerting force upon the lever A. The lower end of the lever A is shown forked and fitted upon the roll A, which rollis shown movably secured upon the stud A (shown also in detail in Fig. 10 under Fig. 3) and is prevented from coming off of said stud by the hexagon nut shown on said screw in Fig. 3. When the rod A (shown at the bottom of Fig. 3 and in detail in Fig. 10) is moved toward the right in practice by the cam A, as hereinabove described, thereby carrying the roll A, the lever A shown connected with said roll, is moved toward the right by said roll and the flange of the feeding device A is gripped by said lever and the lower part of said feeding device is carried toward the right and the upper part of said feeding device is thereby carried toward the left in order to move the leather toward the left or toward the rotatory disk skiving-knife A and the folding and rubbing device A, and the coil-spring A shown secured to the hook shown in the lever A and to the screw shown in the bracket A is expanded or stretched beyond its normal length, and the spring A (shown in Fig. 3 secured to the screw shown in the sleeve A shown on the rod A and shown secured to the screw shown in the bracket A) is also expanded, which spring A moves the rod A toward the left in practice, the cam A permitting, thereby moving the lower end of the lever A toward the left, allowing the spring A, shown secured to the hook in the lever A to move or slip the lever A toward the left upon the flange of the feeding device A, while the feeding device A is prevented from being moved by this movement by the cylindrical check or trig A forced down in the V- shaped opening (shown in Fig. 3 by dotted lines) between the face of the feeding device A and the back of the slot in the device A (shown also by dotted lines) by the spring A", shown secured to the device A 7 by the screw A In Fig. 2 the bottom part of the presserfoot B is shown above the feeding device A and near thereto. The screw having the hexagon head shown in front of the presser-foot- B is inserted in a slot shown by dotted lines in the presser-foot under the hexagon head and is. threaded in another piece in the manner shown in Fig. 3, clamping the presserfoot B to the other piece by said screw, as is shown in Fig. 3, and leaving the presser-foot adjustable to the right and left on the piece to which it is secured, as is plain by this construction in Fig. 2. The piece to which the presser-foot B is thus secured thereby becomes a part of the presser-foot B. This part to which the presser-foot B is thus secured is movably secured to the arm B (shown in Figs. 2 and 3) by the two screws shown in Fig. 2 immediately above the hexagon screw, which screws extend through the slot in the upper part of the presser-foot B (shown by dotted lines under the round heads of said screws) and are threaded in the arm 13*, which is rigidly secured to the frame A, affording an adjustment of the presser-foot up and down. Therefore it is plain by the devices shown in Fig. 2 and the description thereof. that this presser-foot is rigidly secured, but is manually adjustable toward the right and left and is also adjustable up and down.

The presser-bar 13 is shown in Figs. 1, 2, and 3 movably secured in the arm B Upon the presser-bar B between the bearings in which it is movably secured, a collar is shown rigidly secured to said presser-bar B Resting upon this collar the end of the long flat spring B is shown, which spring presses the presser-bar B downward with great force as far as the knurled nut on the top of the 'presser-bar B permits. Said flat spring B is secured to the arm B by the first screw flat spring is forced down upon the collar of the presser-bar B thereby forcing the presser-bar downwardby the second screw at the left from the screw B in the arm B (shown also by dotted lines in Fig. 2,) which screw is shown knurled in Fig. Sand extends through a slot ,in thespring B andvis threaded into the frame A by which screw the amount of pressure upon the presser-bar B may be manually governed. Upon the bottom of the presser-bar B the presser B is shown in Figs. 2 and 3 rigidly secured,

which presser B is normally held and yieldingly supported at such an elevation'above the device A on account of the above-described devices that the skived part of the leather'before it is folded may be moved under the presser B without binding theleather;

' but the folded part of theleather being thicker than the skived part of the leather is forced against said presser B in practice and rubbed by the highest portion of the-operative part described, the-part of leather near the edge of.

skiving-knife little by little near the edge of. i

of the device A at proper times. When the feeding device A is moved in practice intermittently or little by little, as hereinabove the leather is thereby moved intermittently between the presser-foot B and the feeding device A and is moved intermittently against the cutting edge of the rotatory disk skiving knife A at an angle to said cutting edge of said rotatory disk skiving-knife by said feeding device, and said leather is skived by said said leather and shaped like a wedge on account of the intermittent movement imparted to the leather by said feeding device and is intermittently moved up on the device A I for folding and rubbing the skived part of the leather, the body of the leatherbeing toward the left, and the skived part is slit and folded, as and by devices hereinafter described,

, as it is thus passing, and the shaving cut from said leather as it is thus passing falls upon a sheet-iron chute of, common construction,

which chute is secured tothe frame A and verynear together.

isadapted to preventthe shavings from getting into the operative mechanism of the machine. The position ofone side of this chute is indicated atthe left-hand side of Fig. l by a dotted line outside of the frame A near to said frame and extending parallel with said frame, said dotted li'nepassing through the heating device D and the othertwo sides of said chute are indicated by two dotted lines This chute is also shown.

Q inother figures; but no reference character is placed thereon, because reference to the chute is not considered necessary, as nothing new is claimed in the construction thereof,

and because the chute is not a part of the operative mechanism whereupon the unitary result of the invention is accomplished, the

use of said chute being wholly to prevent the shavings from falling into the operative mechanism of the machine.

. Having shown and described the mechanism comprising the rotatoryd isk skiving-knife A and .the feeding device A yieldiugly supported and the means whereupon the feeding device A is automatically moved intermittently little by little in order to move the leather little by little intermittently against the cutting edge of said rotatory disk skiving-knife A and having also described the general shape and constructionv of the device A for folding the skived part of the leather and for rubbing the folded part of the leather from the folded edge inward and set forth the operation of the feeding device A and the rotatory disk skiving-knife A and set forth the result accomplished on account of said skiving-knife and feeding device, it should be understood that I do not broadly claim all kinds of devices whereupon the leather may be moved intermittently or otherwise, but only those which are comparatively the same as the feeding device shown and described. Attention is called to the specific construction and novel features of the device whereupon the skived part of the leather is folded and rubbed from the folded edge of theleather inward. In Fig. 3 this device A is shown in side elevation. In Fig. l the device A is shown in plan and is inclosed by the largest circular line in the view. The next to the largest circular line indicates the top of the bevel shown in side elevation iuFig. 3. Attention is particularly called to this bevel, the device itself being made thick fol-strength and beveled like a wedge. It should be fully understood that, as. it is hereinabove described, this device A is rotatable and that the direction of its movement is from the skived edge of the leather inward at about right angles to said skived edge, and it should be fully realized that this device A, made thick for strength and beveled for utility and recessed as and for the purpose hereinafter described and adapted to be rotated and moved from the skived edge inward, is regarded as the chief device of this invention. In actual construction the operative part of the device A (shown in Figs.- 1, 2, 3, and 15) or, in other words, that part of the device A which contributes in the production of the folded edge by acting upon the leather is designed to beirregular, or, in other words, some portions of the operative part of the device A are designed to be higher than other portions of said operative part. The operative part of the device A is shown recessed clear through the device A from the inclined portion 13 of the operative part of the device A to the inclined portion of the operative partof the device A, (indicated by the first reference character Z atthe left of the reference character E because the recess shown as extending clear through the device A shows the operativeness of the invention better than it would if it were shown as not extending clear through the device A, and besides this recess another portion of said operative part of the device A is shown recessed from the inclined portion indicated by the, reference character Z to the inclined portion thereof indicated by the second reference character Z near thereto, which recess Z Z is not shown as extending clear through the device A Therefore it is shown by Figs. 1, 2, 3, and 15 that said operative part of the device A is recessed at various places to various depths, and also that said operative part of the device A comprises a surface some parts of which are higher than other parts. This device is not only a folding and rubbing device, but it is also a cementing device, or, in

.other words, a device for depositing cement upon the skived surface of the leather before it is folded, as will hereinafter appear. Upon the horizontal part of the recessed portion Z Z of the operative part of the device A cement is mechanically deposited in practice as and by devices hereinafter described and is deposited upon the skived surface of the leather before it is folded in practice by said recessed portion Z Z as and by devices hereinafter described. The reason why that the portion Z Z of the operative part of the device A is made lower than other portions of said operative part is that if it were not so the cement would be distributed over the surface of the highest portion of the opera tive partof the folding and rubbingdevice A, or, in other words, upon that part which rubs the folded part of the leather after it is folded, and this is undesirable; but on account of the portion Z Z of the operative part of the device A, upon which cement is deposited in practice as and by devices hereinafter described, being made lower than other portions of the operative part of the folding and rubbing device A cement is deposited in practice upon the skived surface of the leather by said recessed portion Z Z of the operative part of' the device A before the skived part of the leather is folded, thereby enabling the highest portion of said operative part of said folding and rubbing device A to rub in practice the opposite side of the leather from the side on which cement is deposited, thereby preventing cement from being distributed upon said highest portion. Therefore the operative part of the device A, comprising recessed portions and a surface some parts of which are higher than other perts, is a distinct novel feature of this invention.

Having shown and described that the device A for folding and rubbing the skived part of the leatheris also acementing device for depositing cement upon the skived part of the leather before it is folded and stated that cement is deposited in practice upon a recessed portion of the operative part of the device A for folding and rubbing the skived part of the leather as and by devices hereinafter described and that cement is rubbed in practice by said cementing device upon the skived part of the leather, attention is called to the description of the receptacle in which "receptacle.

cement is kept and the devices whereupon cement is automatically taken in practice from said cement-receptacle and deposited upon said recessed portion of said operative part of said device A. The cement-receptacle C (shownin detailin Fig. 13)-is in practice manually filled with cement. Two projections orlegs are shown upon the front side of said receptacle 0, standing out from each upper corner of said receptacle, and a round holeis shown through each projection or leg. Said cement receptacle 0 is secured to the frame A as shown in Figs. 1 and 3, by screws (shown by dotted lines) extending through said holesin said projections or legs and threaded into the frame A and said receptacle is also shown secured to the bracket A by two fiat-head screws, (shown at the eX- treme left in Fig. 3,) extending through the bracket A and threaded into the bottom of said receptacle. The shaft 0 is shown journaled in said cement receptacle and extends through said cement. Fast upon said shaft is the cement-wheel C shown projecting above the top of the cover of said Movably secured to said shaft C is shown the pawl-carrier O A spring C is shown fast to said receptacle and bears against said pawl-carrier C and normally forces said pawl-carrier 0 against the screw 0*, shown fast in said receptacle. Fast in said pawl-carrier C is shown a piece of rawhide C The pawl C is loose upon the screw 0 which screw is shown fast in said pawl carrier. shown held in contact with the ratchet C by the spring C shown fast to the screw 0 shown in said pawl, and the screw 0 shown in said pawl-carrier, and said ratchet is shown secured to the shaft 0. A device or striker O is shown in Figs. 9 and 1 secured to and adapted to be carried by said device A. It is plain by Fig. 9, in which a section of said device A is shown, that the device or striker O is carried by the device A into contact with the rawhide 0 (shown in Fig. 13,) fast in said pawl-carrier 0 every time said device A is rotated. It will be observed that said pawl-carrier is thereby moved a short distance in one direction by said device or striker every time the rawhide 0 fast in said pawlcarrier, is struck thereby, thereby forcing the pawl 0 carried by said pawl-carrier C to engage and turn the ratchet 0 the shaft 0', secured thereto, and the cement-wheel 0 fast to said shaft, intermittently or little by little, thereby taking cement out of said receptacle on the face of said cement-wheel O at every revolution of the device A the spring moving the pawl-carrier C in'the opposite direction from the direction in which it is moved by the striker 0 every time it is moved by the device or striker C After cement is in practice thus automatically taken out of said receptacle upon the face of said cement-wheel O the cement is mechanically taken from said cement-wheel and is The end of the pawl O is mechanically deposited upon the recessed about the same time that cement is taken out i of said receptacleon account of devices de- (in Figs. 1, 2, 3,114, and 15.

and 16.) Said cover 0 is shown secured to the bracket 0 bythe screws 0 and C (Shown in the upper part of Figs. 1 and 14 and also near the left-hand upper corner of Fig- 3.) Said coverC is also shown secured to the brackets C and C by the screws O C C and 0 as shown in Figs. 1, 14, and

16. These brackets are secured to the co: Inent-receptacle O, as is plainby Figs. 1, 14, and 16. There is a part C (shown in Fig. 2,) fast to said cover 0 that extends toward the right. Said part is shown fast upon the frame A Thus-itis plain that said cover 0 is supported at four different places. Every time that said deviceA is rotated said cam 0 (shown inFigs. 1, 2, 3, 1:4, and 15,) fast to said deviceA", is rotated. The cement-brush bar 0 shown mounted in the ways C and 14, 15, and 16,) is shown held against the cam C by the coilspring 0 shown fast to a pin 0 shown in said cement-brush bar, and to a pin C shown fast in said cover 0 Therefore itis plain that said cement-brush bar C is moved in practice inone direction by said cam (3 and in the opposite direction by said coilspring 0 In Figs. 1, 3, 14, and 15 the ocment-brush G is shown bearing upon the cement-wheel C in the position it is in practice taking cement from said cement-wheel.

Itis plain by the shape of said cam 0 (shown in Fig. 1,) that said cement-brush is moved in practice from the position shown in said figures to the recessed portion Z Z of the operative part of said device A hereinabove described,which recessed portion Z Z is shown in Figs. land 15, and that cement is taken in practice from said cementvwheel C bysaid cementbrush C and deposited upon said recessed portion Z Z of said operative part of said device A The construction of the cement-brush G is shown in Fig.17. Said brush is made of bristles by pulling them double into the hole in said brush-bar by the wire C and the end of. the wire 0 is secured by the screw 0 thereby securing the bristles in said brushbar; but the device for taking cement off from said cement-wheel C is not restricted to this 1 form, but may be any device suitable for the purpose for which this brush is used.

I believe that such devices have not been heretofore devised, whereupon cement taken out from a cement-receptacle is then taken and deposited upon the skived surface of a piece of leather, and Ialso believe that such means have not been combined with operative parts of skiving-machines or skiviug and folding machines and have not heretofore contribu ted in the production of a folded edge, and therefore I believe that the devices employed in this machine, whereupon cement is taken from said cement-wheel and deposited. upon the skived surface of the leather, form a novel combination of devices comprised in this invention, which combination contributes to the production of the unitary result of the machine-via, a folded edge.

The thumb-screw C (shown at the lefthand lower corner of Fig. 3 and shown also in Fig. 1) extends through a hole in the frame A fitting loosely in said hole, the head of said screw bearing against the outer side of said frame and a collar fast to said screw hearing against the inner side of said frame, said is worn so small that the cutting edge thereof is not in the the edge of the proper relative position with operative part of the device A the adjustable knife-shaft support A may be loosened on the frame-A by said handscrew, and the knife-shaft support, with the knife-shaft A mounted therein, and the rotatory disk skiving-knife A", secured to said shaft, may be manually forced forward in practice by said thumb-screw 0 until the cutting edge of said skiving-knife A isiu the proper position, and then said knife-shaft supportA may be again firmly fixed or secured to the frame A by said hand-screw. It should be understood that the means whereupon said skiving-knife may be thus moved into position after it is worn so small that it is out of proper relative position with the edge of said operative part of said device A for folding and rubbing is also a novel feature of this invention.

There are operative devices in this machine-via, devices whereupon the slitting of the skived part of the leather at'aboutrightangles to the skived edge of the leather is accomplished--which contribute tothe unitary result attained by the machine-viz., a folded edge-which devices have not been heretofore described; but as the nature of the entire combination of devices or this machine screw being also threaded into the bottom of deliberation it has been deemed best that they be described in the operation of the machine, which is as follows: The leatheris moved about one-eighth of an inch in the manner hereinabove described by the feeding device A operated by devices herein-above described, against the skiving-knife A", and

is thereby skived a short distance or about one-eighth of an inch, and the device A is so timed with the devices whereupon the feeding device is moved that the leather is moved in upon said recessed portion Z Z, (shown in Figs. 1, 2, and 15,) and the cam-surface A on thewheel A (shown in Fig. 3) is forced into contact with the roll A (shown in Figs.

1 and 2,) which roll is movably secured to the Fig. 1, the reference character thereon being near the pivotal point of the lever B in Fig. 1 in such a manner as to move the link 13, (shown in Fig. 2,) pivoted to the lever B by the screw B", upward against the power of the spring B secured to a screw in the arm B and to a screw in the link B and moving the right-hand end of the lever B pivoted to the link 13 by the screw 13, upward upon the pivot B fast in the arm 13, thereby moving the left-hand end of the lever B downward and carrying the link B pivoted to the lever B by the screw B and the bracket B pivoted to the link B by the screw 13, and the knifebar B movably secured to the arm B and rigidly secured to the bracket B downward, thereby carrying the bending device or spring 13, shaped somewhat like the letter J and secured to the lower part of the knife-bar B the lower end of which bending device is shown in Fig. 2 by dotted lines behind the knife B fldownward, the thickness and width ofthe lowerend of which bending device are shown by dotted lines in Fig. 3, thereby pressing the skived part of the leather down upon the recessed portion Z Z of the operative part 7 of the device A, which bending device B is thereby forced to yield or bend, and the knife B (shown in Figs. 2 and 3,) the lower end of which knife is beveled like a chisel and sharp, which knife is fast to the lower end of the knife-bar B is forced by said knife-bar down upon the skived part of the leather, one side and cutting edge of said knife shearing past and rubbing the shearing device or block 13", rigidly secured to the frame A and shownin Fig. 2, and the other side of said knife almost rubbing against the periphery of the moving device A thereby cutting a slit about one-eighth of an inch long through the leather and at about right angles to the skived edge, thereby disconnecting the skived part from the part not skived, and the cement deposited upon said recessed portion Z Z of the operative part of the device A as and by devices hereinabove described ,is rubbed upon the skived surface of the leather, and the recess or opening in the inoperative part of the device A which device is being moved in the direction indicated by the arrow shown thereon, is mechanically carried under the part of the leather upon which the bending device B is pressing, whereupon the skived and slit part of the leather is bent downward by the spring 13 into said recess or opening and is instantly caught and folded under by the inclined portion B and is rubbed in the direction of the folded edge inward by the highest portion of the operative part of the device A, which device is hot, being heated by the gas device D, as hereinafter described, said skived part of the leather being firmly but yieldingly held down upon the highest portion of the operative part of the device A, while the folded part is rubbed by the presser B fast to the presser-bar B (shown in Figs. 2 and 3,) which presser-bar is movably supported in the arm B and firmly but yieldingly held down by the spring B (shown in Figs. 1, 2, and 3,) secured to the arm B by a slotted screw (shown by dotted lines in Fig.

2) at the left of the pivot-screw B in the arm B, said spring 13 being held downward upon a collar shown secured to the presser-bar B in Figs. 2 and 3 by a thumb-screw, (shown by dotted lines in Fig. 2 at the left of said slotted screw,) said thumb-screw extending through a slot in said spring and threaded into the arm B Repetitions of the above-described operation produce a folded edge of a piece of leather that may be thicker, but substantially the same thickness as the leather before it is folded.

I do not broadly claim all kinds of devices whereupon slitting may be accomplished, but only those which are comparatively the same as the devices whereupon the slitting is accomplished shown and described.

Let it be understood that the invention of the device A, adapted to apply cement and to fold and rub, as hereinabove described, the rotatory disk skiving-knife A, the slitting or shearing device B, the feeding de- A the bending device B, the presser B and the presser-foot B, each and all made substantially as shown and described, and the combining of these devices substantially as shown and described, so that they may all cooperate together upon the leather in proximity to each other, as described, so that a folded edge can be made upon parts of shoes which have short curves, is the result of very severe and protracted taxation of my creative faculties and, as this is the first machine whereupon parts of shoes could be skived and folded around short curves, is very important.

In order that all the cement that is placed upon the recessed portion Z Z of 'the operative part of the device A may be used upon the leather every time said cement is put in practice upon the recessed portion Z Z,as

The deto the t cover of said receptacle by the screw 0 extending through the slot shown in said device C and threaded into the cover of said receptacle, which device G is also movably connected with the thumb-screw C which extends through and fits loosely in a holein the device 0; the body of the thumb-screw bearing against one side of the device 0 as shown in Fig. 13, and a collar (shown in Fig.

1) fast to said thumb-screwbearing against the other side of the device 0 may be moved toward or from the cement-wheel O by the thumb-screw O thereby placing the chiselshaped end of the device 0 ata proper dis- (3 to allow the cementout of the receptacle 0, or, in other words, to allow said cement-wheel C to take cement out of said receptacle just as fast as it is needed upon the leather, whereupon the accumulation of cement upon the recessed portion Z Z of the operative part of the de j vice A is prevented. It will be observed that this cement-receptacleis so made thatit is nearly air-tight in order that the liquid in the cement therein may not evaporate. It is plain that before the unitary result of this machine-vizL, afolded edge can be pro duced-saidskiving-knifeA"mustbe ground or sharpened. Therefore, the mechanism whereupon said skiving-knife may be mechanically ground or sharpened is a component part of the machine which is the subject 34 j Figs. Stand 1, the upright shaft D is shown journaled in the bearings D and D which bearings are shown fast to the frame A shaft D is bearings of said emery-wheel-shaft support.

said shaft is shown the friction-Wheel D of the present application and is shown in the drawings and is described as follows: In

Shownfast to said shaft Dis the emery-wheelshaft support D,having a handle, near which the reference character D- is placed, said emery-wheel-shaft support D also having two arms, the upper one of which is designated in I .FigsQl and 2 by the reference character D ,and f 5 each one of these arms supports ajotirnal-bear ing. (Shown in Fig.2.) The emery-wheel shown journaled in said journal- In said shaft is shown the groove 'D. Upon The screw D is shown screwed tightly into said I shaft D frictionwheel, and the point of said screw fits loosely in said groove D in said emery-wheel Therefore it is plain that the friction-wheel D is rotated in practice with said I shaft, but is movable vertically upon said shaft. Above said friction-wheel D -aud bear-.-

ing against said friction-wheeland around said shaft D is shown the coil-spring D, the end of which enters into thecollarshown upon the shaft D above said spring, which collar is shown secured to the shaft D by a 2, to pull the emery-wheel-shaft wheel D' is shown in detail, and a ring, of rawhide, D is shown secured upon the inclined part of said friction-wheel. The grinding of said skiving-knife A- may. be accomplished by the emery-wheel D (shown fast to said shaftD ,)as follows: Thehandleofsaid emerywheel-shaft support D (shown in Figs. 1 and 2) may be moved in practice by hand, thereby moving the shaft D, 1,) secured to said emery-wheel-shaft support D and mounted in the journal-bearings D and D the emery-wheel shaft D shown rotatably secured in the journal-bearings of said emery-wheei-shaft support, and all the devices shown secured to said emery-wheel shaft, thereby forcing the inclined rawhide surface D (shown in Fig. 11) of the frictionwheel D (shown also in Figs. 2 and 1) into contact with the inclined surface of the fric- Lion-wheel D (shown in Fig. 3 and shown also in Fig. 2,) secured bya screw to the skiving-knife shaft A which friction-wheel is rapidly rotated by the skiving-knife shaft A to which said skiving-knife A is secured, and thereby forcing the emery-wheel D secured upon the top end of said emery-wheel shaft D 7 its cutting edge, and thereby forcing the friction-wheel D upward upon the emery-wheel shaft D against the force of'the coil-spring D whereupon the friction-Wheel D the emery-wheel shaft D and the emery-wheel D are rotated, thereby grinding said skivingknife. After said skivingknife is ground sharp the handle D shonld be released, thereby allowing the coil-spring D (shown by dotted lines near the right-hand lower corner of Fig. 1,) secured to the emery-wheel-shaft. support D and to the inside of the frame A a part of which spring is also shown in Fig. support D the emery-wheel shaft D and all the devices secured to said emery-wheel shaft back in the opposite direction from that in which they are moved by hand and to thereby cause the grinding to immediately cease.

The device A (shown in Figs. 1, 2, and 3) is heated in practice by the gas device D. (Shown in Figs. 1, 2, and 12.) The construc-. tion of this gas device is shown in detail in Fig. 12. The tube D is shown broken. If gas were applied directly from a gas jet or tip againstthedeviceA andif it were lighted .while thus applied, in a few minutes said device would be covered with lampblack from the smoke caused by the burning gas. To prevent the accumulation of lampblack,the gas device shown in Fig. 2 is employed. The

draft of the lighted gas inside of the gas de .vice draws air in at the holes D and D in the bottom of said device in blue flame is thereby forced said gas device through the hole D practice, and a out of the top of This flame is practically free from smoke by which (shown in Figs. 2 and against the skiving-knife A near panying drawings of a machine in which this invention is embodied and having carefully set forth the novel features and combinations of this invention, I claim as follows:
